Low Cost Field Development using Hybrid Risers

Surplus rigs in the drilling market is an opportunity to reduce CAPEX by up to 50% and time to first oil by one year compared to an equivalent TLWP.

There have been many drilling rig conversions over the last 35 years, mostly to production platforms, except for Luihua which is a drilling and WO semi in 300m water depth moored over a cluster of subsea trees.

Subsea trees and freestanding risers enable a MODU to be repurposed as a permanent moored drilling and workover vessel for deepwater.
